Description

Technical Field

[0001] The utility model relates to a lifting tool for large aluminum alloy round bars out of a well, belonging to the technical field of aluminum alloy casting. Background Art

[0002] Aluminum alloy round bars are formed from molten aluminum into solid round bars through a mold. The current casting process is semi - continuous shaft casting, and the number of castings per time is about several to dozens. After casting, multiple aluminum alloy round bars stand vertically in the casting well. The casting well is lower than the ground plane of the workshop, and the cast aluminum alloy round bars need to be lifted out of the casting well and placed flat on other equipment to enter the next process using a lifting tool.

[0003] Although the existing lifting tools can perform daily lifting operations on large aluminum alloy round bars, in actual use, the method of lifting out of the well by chain bundling is adopted. In the use of small - sized round bars, since the mass of a single aluminum alloy round bar is small, the chain used has a small load - bearing capacity, so the chain is light in mass and it is a bit easier for manual operation. However, for large - sized round bars, the self - weight of a single bar is heavy, and the matching chain is also heavy. It is very laborious for workers to pick up and bundle, which brings inconvenience to the use of workers, and further makes the convenience of the lifting tool for getting out of the well insufficient. And because the chain is composed of multiple single chain links, and each single chain link is welded, the welding quality directly determines the safety of the chain, there are relatively large potential safety hazards. In actual use, there may be accidents such as the loosening or even breaking of the welding joint of a single chain link under sudden stress, resulting in the dropping of the round bar, which further makes the safety of the lifting tool for getting out of the well insufficient.
